<h3>The salary of Perry if inflation is 6.5 % is $ 32617.475</h3>

<em><u>Solution:</u></em>

Given that,

Perry made $34,885 this year

The inflation rate was 6.5 percent

To find: Salary worth if inflation rate was 6.5 percent

From given,

Inflation rate = 6.5%

Therefore,

Worth of salary due to inflation = 100 % - 6.5 % = 93.5 %

Money earned in this year by Perry = $ 34, 885

Therefore,

Worth of Perry salary due to inflation = 34,885 x 93.5%

\text{Worth of Perry salary due to inflation }= 34885 \times \frac{93.5}{100}\\\\\text{Worth of Perry salary due to inflation }= 34885 \times 0.935\\\\\text{Worth of Perry salary due to inflation }= 32617.475

Thus the salary of Perry if inflation is 6.5 % is $ 32617.475

Suppose a team of doctors wanted to study the effect of different types of exercise on reducing body fat percentage in adult men
Inessa05 [86]

Answer:

<em>A. The F statistic increases as the differences among the sample means for the exercise groups increase.</em>

<em>C. The F statistic has 3 degrees of freedom in the numerator and 35 degrees of freedom in the denominator.</em>

<em>F. The F statistic is 9.2242.</em>

Step-by-step explanation:

Given that

Observations                     Samples                             Total

40-49             10       11              9         9                        39

The degrees of freedom is given by

For numerator= k-1 = 4-1=3

For denominator= n-k= 39-4= 35

F statistic is given by

F= MS between/ MS within

=11.632991 / 1.261143 = 9.2242

Where

Mean Square Between = MS between = 11.632991

Mean Square Within = MS within = 1.261143

<u>Hence the correct choices are  A, C and F</u>

<em>A. The F statistic increases as the differences among the sample means for the exercise groups increase.</em>

<em>C. The F statistic has 3 degrees of freedom in the numerator and 35 degrees of freedom in the denominator.</em>

<em>F. The F statistic is 9.2242.</em>

<em></em>

Suppose we have

Mean Square Between = MS between = 18.632991

Mean Square Within = MS within = 1.261143

Then F statistic would be = 14.77468 > 9.2242

which tells that <em>The F statistic increases as the differences among the sample means for the exercise groups increase.</em>

MANUFACTURING A shoe manufacturer spends $2.50 to make sandals and $4 to make running shoes. During a typical month, they spend
jonny [76]

Answer:

200 pairs of sandals

Step-by-step explanation:

Represent the sandals with x and the running shoes with y.

In a typical month:

Total = 2500

In April

Total = 3000

Required

The number of sandals in a typical month

<u>In a typical month:</u>

If 1 sandal costs 2.50, then x costs 2.50x

If 1 running shoe costs 4, then y costs 4y

The total is:

2.50x + 4y = 2500

<u>In April:</u>

If 1 sandal costs 2.50, then 2x costs 5x ---- <em>we used 2x because the pairs is doubled </em>

If 1 running shoe costs 4, then y costs 4y

The total is:

5x + 4y = 3000

The equations are:

5x + 4y = 3000

2.50x + 4y = 2500

Subtract

5x - 2.50x + 4y - 4y = 3000 - 2500

2.50x = 500

x = \frac{500}{2.50}

x = 200

Explain how to find 3/4 of 20 using a model. Include a drawing
Igoryamba
Ok so it would be 3/4 times 20
And you would get 15
I would draw a circle that adds up to 100
To do this multiply the 20 five times to get 100
Then multiply the 15 by the same number (5) to get 75
Draw a circle and shade in 75% of it and that is your answer
